Product Overview

  • Control from across the room or across the country via mobile app
  • Reduce energy usage with geofencing, scheduling and remote access
  • Works with Apple HomeKit, Amazon Alexa and Google Assistant
From across the room or across the country, your Sensi Wi-Fi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere. Designed to work with the wires you already have, Sensi thermostat does not require a common wire (c-wire) for most installations, so it is compatible with the HVAC equipment in many homes in U.S. and Canada. A c-wire is required for heat-only, cool-only and heat pump (without aux) systems and for use with Apple HomeKit. Check to make sure it will work for you at sensicomfort.com/compatibility. The intuitive app walks you through each step of installation with custom configured instructions, removing all the frustration and guesswork from the installation process so you can be up and running in no time, no experience required. Put your comfort on your terms using location-based temperature control with geofencing or creating custom heating and cooling schedules with the flexible 7-day scheduling option. Both energy saving features help to reduce your HVAC related energy costs so you can save money without compromising your comfort. Plus, Sensi integrates directly with Amazon Alexa, Apple HomeKit and Wink home automation platforms and works with Google Home and Google Assistant via the free Wink app. Connect to Amazon Alexa to control your home temperature with simple voice commands or just ask Siri to set, raise or lower your home temperature when using Sensi with Apple HomeKit.

Sensi 7-Day Programmable Wi-Fi Thermostat and Wall Plate Bundle is rated 4.3 out of 5 by 146.
Rated 5 out of 5 by from Works well and simply to use and setup. I had it working in 30 minutes. The instructions to insta... Works well and simply to use and setup. I had it working in 30 minutes. The instructions to install this thermostat should be the gold standard for instructions. It was a simple step by step instructions on your iPad with videos if you got stuck. The thermostat works great remotely and it even tells you the humidity in the house and the local weather all on one display on your remote devices. Easy to tell if everything is working. The thermostat itself has a large read out, easy to see even without glass, on only the important info displayed, temp set and current temp, time, battery condition (runs on AA), heat/cooling mode, fan mode and schedule on/off (this one is so smart and if you are on vacation and want to set one temperature) One concern is the thermostat clips onto the plastic bracket, we will have to see if the clips last. So far they seem fine and you would only have to take it off to change the batteries. To I don't think it is a big issue. All in all a great thermostat.

Rated 1 out of 5 by from Large and Bright Readouts, easy to install and use with the step by step installation instruction... Large and Bright Readouts, easy to install and use with the step by step installation instructions that is via an app. The downfall was the wifi. No matter what, the wifi would not connect. Spoke with Sensi, they said my router was not compatible, so they sent me a new router to be used only with the Sensi. Guess what....after an hour plus on the phone with tech support (Sensi'sTech support people are great!) it would just not connect. I thought maybe it was the thermostat, I bought two and only installed one. Tried the other thermostat and the same situation occurred. I really liked the product, too bad the wifi did not work. As I read the posts on this site, I see I am not the only one with the connection issue.No other choice but to return them to Home Depot and purchase another brand.

Rated 5 out of 5 by from Very satisfied Understand what you're getting and ensure it's what your expectations are. I didn't want to spend $200-$500 on a high-end, wireless, smart thermostat like a Nest. I needed a new thermostat as my old, 1990's one died. I wanted something that was easy to install, which this was. I wanted something that had a basic, simple, touch screen as well as smartphone capabilities. This knocked it out of the park on those features. It doesn't look as fancy as a Nest, nor does it have as many features. But for the money? I think it's AWESOME. It even sends me email alerts if it senses the humidity is too high in the house, which I laughed at the first time, but it's a nice perk with it. It really boils down to the features you 'need' and want as well as how much you're willing to spend. <$120 for a smart, wireless thermostat that was easy to install, has a touch screen, and easy to use app? Sign. Me. Up.

Rated 5 out of 5 by from This is a great product. I have installed three in two locations. Since no C wire is required, ... This is a great product. I have installed three in two locations. Since no C wire is required, installation is a snap - < 5 mins. In one location, the furnace is 3 years old - Sensi works great without a C wire. However, in the location with the 20+ year old control board, it requires a C wire connection to work correctly. Without the C wire, the wifi dropped constantly and the unit fan relay ran intermittently. Called Emerson, they suggested electrician. But on-line advice showed that the Wifi thermostats aren't really battery powered - without a C wire they "steal" power from the control board via the R and W wires. Learned also that the "power stealing" function of this (and other new Wifi thermostat) interferes with the old (1990s) Lennox control board operation. Running a new C wire from the control board to the Sensi fixed the problem (took about 20 mins). The wall plate is great to cover up old holes in wall!
